Abstract

La présente invention concerne un exemple de dispositif de communication sans fil, qui comprend un processeur couplé à une mémoire et une interface de communication sans fil. Le processeur est configuré pour transmettre un premier symbole de transmission à un premier index temporel depuis un premier jeu d'index temporels et pour transmettre un second symbole de transmission à un second index temporel différent du premier, une partie du premier symbole de transmission et une partie du second symbole de transmission incluant les mêmes données. Le premier jeu d'index temporels est associé au premier identifiant de dispositif et comprend au moins un index temporel qui n'est pas contenu dans un second jeu d'index temporels associés à un second identifiant de dispositif et le second jeu comprend au moins un index temporel qui n'est pas contenu dans le premier jeu.
